Warren grew up in Conley, Georgia, a suburb of Atlanta, and attended Forest Park High School, where he played football and participated in the Air Force Reserve Officer Training Corps.
[1][2] Warren played defensive back at Air Force and graduated in 1999 with a bachelor's degree in human factors engineering.
New head coach Troy Calhoun retained several graduate assistants from DeBerry's staff, including Warren, Singleton, Brian Knorr, and Blane Morgan.
Warren recruited the state of Georgia well, but Air Force's defenses ranked among the worst in NCAA Division I Football Bowl Subdivision.
Knorr stayed at Air Force for all of ten days before taking the defensive coordinator job at Indiana University; Matt Weikert eventually filled the position.
Beyond improving the pass defense, there was an expectation that Warren could help recruit the Atlanta area, where a resurgent Georgia until Kirby Smart had made significant inroads.
Pruitt did not retain Warren on his staff, but he was quickly hired by Dan Mullen at the University of Florida, also in the SEC, as the cornerbacks coach.
